TO ALL WHOM 1T MAY CONCERN:

Be it known that I, ERNST GESSNER, of Aue, iu the Kingdom of Saxony,have invented a new and improved Teasing Attachment to vrigh-Iills; andI do hereby declaro that the following is a`full, clear,l and exactdescription thereof, which 'will enable others skilled in the art tomake and use the same, reference being had to the accompanying drawing,forming part of this specification, in which- Figure 1 represents atransverse vertical Asection of this invention.

Figure 2 is a. front elevation of the same. I

Similar letters of reference indicate like parts. v y This inventionrelates to an attachment to gig-mills which is composed of a series ofrevolving'disks, with cards or other suitable material, which act inconjunction with adjustable guide rollers in snclt s. manner that by therevolving motion of the disks', and by their position in relation toeach othcr,`the {ibreof the cloth is` acted on throughout the wholewidth of said cloth, and under various angles; and, furthermore, thecards act uniformly and continuously on the surface of the cloth, thusraising the nap perfectly in a comparatively short time.

A represents the frame of an ordinary gigmill, to which I secure, bysuitable clamps or set-screws, a frame, C, which forms the bearings forthe studs. a, on which revolve the disks D. Two or morerows of disks may.be used', and a"revolvingv motion 'is imparted to said dis-ks from adrum of the by means of cords F F,

kwhich extend over suitable pulleys which are secured to the disks D,said cords being arranged in such a.

manner that each drives one half of the disks; but it must bye remarkedthat the uiotion'of the disks may be produced by"any other suitablemeans besides those represented` inthe drawings. The frameC is hung ongudgeons, and to one of' its ends is secured a worm-wheel or a segmentof a worm-wheel, K, into which meshes an endless screw, L, mounted ouashaft to which a revolving motion can be imparted by a handle or crank,M. By turning this crank, the frame C can be brought up or removedfromthe cloth, which is necessary for the purpose lof attaching thecords or changing or cleaning thevsame. It is obvious 'that this motionof the frame can be effected in various dii'erent` ways. The cloth orfabric is conducted to the disks D by means of four rollers, N N. Theouter rollers N have their bearings in arms R, secured to the main framebut the rollers N have their bearings in arins O. O. Thev arms O aremounted on a shaft, P, and they are provided withtoothcd segments on thearms O' so that by turning the shaft the rollers N are brought closer toor removed from the disks-D. On the shaft P'is mounted a toothed segmentwhich gears in a worm, d, to which arevolving motion. is

imparted by a handle, e. By turning this handle the rollers N ,faremoved towards o1"A from the disks D, and

the cloth or other fabric can be brought'in the proper positionv towardssaid disks to produce the desiredoifect.`

By the worm-wheel and toothed segment, the rollers N are retained in thedesired position, and the cloth or fabric being fed along hetwecn therollers N N' and disks D, is acted on throughout its entire width by thecards on the disks, so that thenap of the warp threads and also of theweft threads is raised uniformly throughout.

What I claim as new, and desire tosecure by Letters Patent, is v I I 1.Theconstrnction and arrangement of the revolving disks D in theadjustable frame C, substantially as described for the purposespecified.

2.' The arms O O', with toothed segments, in combination with therollersN and disks D, constructed and operating-substantially as and-forthe'purp'ose seit forth.

This specification signed by me this 28th day of April, 1866. l
